The mass of the nucleus is 2.34348 * 10^(-26) kilogram. The mass of a neutron is always greater than a proton as basically speaking a neutron is composed of a proton and electron and other subatomic particles.

The Nucleus composed from protons and neutrons. In the basic form, in Nucleus, the number of protons equal to the number of neutrons.
The mass of proton is 1.672x10^-27 kg.
The mass of neutrons is 1.674x10^-27 kg.

∙ 13y agoThe nucleus of an atom is made up of protons and neutrons. The number of which varies according to the element.
The more more of these particles there are then the heavier the nucleus will be.

∙ 14y agoThe mass of the neutron is 938,272 013 MeV/c2. There are a number of mesons, and their masses vary according to which one is under inspection. The neutron may be a few hundred to a few thousand times as massive as a given meson, depending on which one it is compared to. Use the link below and check the data table to make comparisons and determine how much heavier the neutron is than a given meson.

∙ 12y ago. In the nuecleous of an atom all the Atomic Mass ( known as a.m.u - atomic mass unit) is found inside the nuecleous. One single proton is 1.0 a.m.u ( or atomic mass unit) and one neutron is 1.0 a.m.u. Electrons have no atomic mass due to the fact that they are constantly moving and anyway would have very little mass.

The most complex atom that occurs in nature has something like 90 to 95 electrons,
but every single proton or neutron in the nucleus of any atom has the mass of
more than 1,800 electrons.

What does the nuclease of an atom not contain?
the nucleus does not contain electrons of the atom.
What part of an atom carries most of its mass?
The vast majority of an atom's mass is within the nucleus; the electrons orbiting the nucleus, which do contain the same amount of charge as the nucleus(albeit negative), have virtually no mass when compared to the nucleus. In fact many scientific disciplines disregard the mass of electrons altogether.
What is the mass number of an atom of chlorine that has 16 neutrons in its nucleus?
All chlorine atoms contain 17 protons in each nucleus. The mass number is the sum of the numbers of protons and neutrons; therefore, the atom described in the question has a mass number of 35.
Mass of atom is contrated on what?
The nucleus of the atom.
What the charge of the nucleus of an atom?
The nucleus is the positively charged central mass of an atom.
Where is most of the mass of an atom contain?
in the nucleus of an atom -proton and neutrons , electrons in the orbit has the negligible mass.
How much atomic mass does the nucleus contain?
This depends on the half-life of the atom
What does the nucleus of an atom not contain?
The nucleus of an atom doesn't contain electrons, but it does contain protons and neutrons.
Why does the nucleus contain most of the atom total mass?
This is because the mass of electron is without importance compared to the mass of protons and neutrons.
The mass of an atom is contained primarily in its?
The mass of an atom is contained primarily in its nucleus.
What does the nuclease of an atom not contain?
the nucleus does not contain electrons of the atom.
Where in the atom is the mass of the atom concentrated?
It is the nucleus. Mass of electrons is too small
Most of the mass of an atom is concentrated in the?
in the nucleus of the atom
What part of an atom carries most of its mass?
The vast majority of an atom's mass is within the nucleus; the electrons orbiting the nucleus, which do contain the same amount of charge as the nucleus(albeit negative), have virtually no mass when compared to the nucleus. In fact many scientific disciplines disregard the mass of electrons altogether.
What does nucleus of an atom have?
The nucleus of an atom contain protons and neutrons; protons and neutrons contain quarks and gluons.
What is the mass and volume of the nucleus?
If you mean the nucleus of an atom, different atom have different masses - an uranium atom has more than 200 times the mass of a hydrogen-1 atom (and most of that mass is in the nucleus).
What is the mass number of an atom of chlorine that has 16 neutrons in its nucleus?
All chlorine atoms contain 17 protons in each nucleus. The mass number is the sum of the numbers of protons and neutrons; therefore, the atom described in the question has a mass number of 35.
